patterns. Also, we use special geologic symbols to indicate 3-dimensionality on our maps. Therefore, a geologic map is nothing more than the representation of 3-d structures on an arbitrary 2-d horizontal plane. Put another way, a geologic map is a cross-section of dipping and plunging structures projected on a horizontal plane.According to that well-established convention, the symbols ka, Ma, and Ga refer explicitly to points in time in powers of 10 3 years before present. Spans of time require a different abbreviation or symbol: m.y. or Myr in the case of millions of years, for example. The critical issue is not whether a single set of symbols will work or whether ...AZIMUTH can be used to Rotate the symbol: Then, find the little abc icon in the Labeling toolbar.
